Order Chain

For some reasons it is usefull to react on sensors (or communication events) with transportation activities. Inside the equipment layer the Devices take that role.

The OrderChain references an UnitLoad to move, its source and its destination.

If an OrderChain is created in the location layer, it will mostly be referenced by an Request, which is the apropriate order class of the location layer.

If a new OrderChain is created, the source StorageLocation needs to be set, the destination StorageLocation and the UnitLoad to transport. Intermediate states may occure in a myWMS system. But to start an OrderChain, at least those three Attributes must be set.

An OrderChain will not go into production before the startOrderChain() of he equipment kernel has been called.

The OrderChain supports handling of priorities. The priority 0 will be preset to an OrderChain. A higher priority will make the OrderChain to be dispatched before concurrent OrderChains of smaller priorities.

Properties

Property fingerprint

Currently there is no formal limitation about the contents of the fingerprint. The fingerprint will be evaluated by external tools, to identify the source of the OrderChain.

The fingerprint may also contain specific operational data for individual devices and components. Even the LoadHandler may use this data to forward it to e.g. an PLC.
